<p>The present invention relates to a single winding mold transformer for supplying power to an electric railway. The single winding mold transformer includes: a core unit (100) which is formed to connect multiple ion cores so that an U shaped core (110) and a V shaped core (120) form a closed circuit; a pair of winding units (210, 220) which is wound by molding resin to be respectively symmetrical in the U shaped core (110) and the V shaped core (120) in left and right sides; and a frame (300) which fixedly supports the core unit (100) by being respectively arranged in the upper and lower ends of the core unit (100) in a horizontal direction. The winding units (210, 220) include: first winding units (211, 221) which have a power supply terminal where power is applied by being arranged in the outermost side of each core; second winding units (212, 222) which are arranged to be separated from the inside of the first winding units (211, 221); and third winding units (213, 223) which are connected with the first winding units (211, 221) by being arranged to be separated from the inside of the second winding units (212, 222). The third winding unit (213) of the U shaped core (110) is connected with the second winding unit (222) of the V shaped core (120), the second winding unit (222) of the V shaped core (120) is connected with the second winding unit (212) of the U shaped core (110), and the second winding unit (212) of the U shaped core (120) is connected with the third winding unit (223) of the V shaped core (120).</p> |
